'Voice' in the Bible

For the children of Israel walked forty years in the wilderness, till all the nation, even the men of war that came forth out of Egypt, were consumed, because they hearkened not unto the voice of Jehovah: unto whom Jehovah sware that he would not let them see the land which Jehovah sware unto their fathers that he would give us, a land flowing with milk and honey.

And Joshua commanded the people, saying, Ye shall not shout, nor let your voice be heard, neither shall any word proceed out of your mouth, until the day I bid you shout; then shall ye shout.

And there was no day like that before it or after it, that Jehovah hearkened unto the voice of a man: for Jehovah fought for Israel.

and said unto them, Ye have kept all that Moses the servant of Jehovah commanded you, and have hearkened unto my voice in all that I commanded you:

And the people said unto Joshua, Jehovah our God will we serve, and unto his voice will we hearken.
